Thank goodness they did it again! After the first infectious Britney Spears-inspired episode last season, Glee is back with "Britney 2.0”—a second tribute complete with a sexy performance of "Oops..." from Lea Michele's Rachel Berry and "Hold It Against Me" from Heather Morris's Brittany S. Pierce (sound it out). The Glee team already unleashed the latter in full, so we're watching Morris—who used to dance backup for Beyonce—and her insane moves on repeat until the new episode debuts tonight at 9/8c on FOX. And the timing is quite fitting, as you can catch the Real Pop Princess as X Factor judge at 8/7c on the same network. So much Britney! UPDATE: Listen to the full line-up of Glee-Britney songs here! Watch "Hold It Against Me" above, and tell us: Which Britney Spears classic do you look forward to seeing the Glee cast perform tonight?
